[ARM] PR82175 - fix -mcpu=native not working correctly.
The new option processing machinery relies on %< rules in the specs to
suppress options that are rewritten. Suppression appears to be a two
phase process where the option is partially suppressed when %< is
processed and then fully suppressed at the end of the string. Strings
are separated by commas and there can be multiple strings used to form
DRIVER_SELF_SPECS.
The fix in this case is to separate the driver self specs for ARM into
separate rules as described; this forces the -m{cpu,tune,arch}=native
options to be properly removed before proceeding to the next rule set.
PR target/82175
* config/arm/arm.h (DRIVER_SELF_SPECS): Separate sub-rules with commas.
